What Cinderella did - sorting the bytes

Hi,

I messed up a gzip'ed tarball by tar's verbose output:

tar -cvzf /dev/stdout /home | split -d -b 4000m - backupPART

I partioned the harddisk and installed fedora 8. My 6 GB '/home' directory is gone. All I got is a messy tarball.

I hope, I can do the Cinderella job: good bytes (gzip'ed data) separating from bad bytes (tar's verbose listing of copied full path file names starting with /home/az and ending at <LINEFEED>).

I'm a newbie and I think textutils are not appropriate. Then I found tr and dd.

I need a little help to realise a nice command or script. My idea is:

read next byte from backup.mess
check if byte.mess == '/' then
check if next 7 bytes == 'home/az' then delete all bytes until <LINEFEED>

But I don't know how to script that. I'll be glad if you give me a hint. Thank you.
